When you have 6 pax onboard with enough fuel to go anywhere,are you still within MTOW????From what I can remember unless atleast 2 of the pax are kids, it's not possible
According to MD's info, the useful load of the 600N is 2,000 lbs. It holds 115 gallons of fuel (784 lbs) - doing the math (2000-784)/6 that still allows six 200-lb pax.
